It really makes me sad to hear this as you were doing so well and were welcomed with opened arms to the needlework community.

All you had to do was source your information and give credit where it’s due. Instead of copying a full article you should have paraphrased (still sourcing/quoting though) and put some of it into your own words with your own thoughts and response to the information.

I will tell you now that once you’ve been blacklisted it is very hard to gain trust and a good reputation back. As stated before I am very sad to see this. Having integrity is always the way to go as you were being supported for your original and honest work.
